3/8" Cordless Impact Wrench

These cordless impact wrenches run on DEWALT batteries and use impact-rated sockets to drive nuts and bolts. The batteries can also power other DEWALT tools of a compatible series and matching voltage. Tools using lower-voltage batteries are generally lighter and more compact but less powerful than tools using higher-voltage batteries. Tools using lower-capacity (Ah) batteries are less bulky but store less power than tools using higher-capacity batteries.
